John McCarthy (September 4, 1927 – October 24, 2011) was an American
computer scientist and cognitive scientist. McCarthy was one of the
founders of the discipline of artificial intelligence. He coined the
term "artificial intelligence" (AI), developed the Lisp programming
language family, significantly influenced the design of the ALGOL
programming language, popularized timesharing, and was very influential
in the early development of AI. McCarthy received many accolades and
honors, such as the Turing Award for his contributions to the topic of
AI, the United States National Medal of Science, and the Kyoto Prize. (Click
